Details of the injury aren't clear at this time, but Murray played the entirety of Saturday's game, a 5-1 home loss to the Montreal Canadiens. Murray also missed time last season due to a concussion.

The 24-year-old Murray is only in his fourth season now, but the injuries have piled up on the two-time Stanley Cup champion. Murray missed 12 games in the 2016-17 season after breaking his hand.

A lower body injury forced him to miss most of the 2017 playoffs, but he took over for Marc-Andre Fleury midway through the Eastern Conference Finals. Murray then guided the Penguins to their second straight Stanley Cup championship.

Various injuries hampered Murray's 2017-18 season, as a concussion, upper and lower body injuries limited him to 45 starts last season. Tristan Jarry (26 games) and Casey DeSmith (14 games), did a fine job in replacing Murray, who has yet to stay healthy throughout an entire regular season.

Murray has struggled through the first two games of the season, yielding a 1-1 record with a woeful 5.47 goals against average and .831 save percentage. He went through an up-and-down 2017-18 season, finishing with a 27-16-3 record, .907 save percentage and 2.92 goals against average.

The Penguins recently re-assigned Jarry to the AHL, meaning DeSmith will likely take over as the starter for as long Murray is sidelined. It shouldn't be a surprise if Jarry gets called back up, however.

Pittsburgh has dealt with many injuries to key players throughout the last four seasons, winning the Stanley Cup in 2017 even though defenceman Kris Letang couldn't play at all in the postseason. When Fleury had to miss the start of the 2016 postseason, the Penguins looked doomed, until Murray came off the bench and led Pittsburgh to the Stanley Cup.

This team is built to get by without its key players, but they have to hope that Murray's absence is short-lived.
